Abstract
The present invention provides a method of testing a transmission line from a copper access network. The transmission line is tested to generate values for a plurality of network parameters. Using previously determined test results, it is possible to calculate an estimate of the length of the transmission line based on the values of each of the measured parameters. These estimates of the transmission line length can then be used to compute a weighted average of the transmission line length. An inference of the condition of the transmission line can be made by comparing the estimates of the length of the transmission line with the weighted average length.
